CJ-2000AX core engine C2XC-101 set fire and reach full speed

Aircraft Engine by the AVIC Commercial Aircraft Engine Co., Ltd. (ACAE)

The core engine of the CJ-2000AX (C2XC-101) set ignition and reached full speed.

At the beginning of 2020, the development of the company's project, that is the Yangtze River 2000 Project (CJ denotes Changjiang or Yangtze River) has made a major breakthrough in the development of C2XC-101 engine core. On March 5, 2020, the engine ignition was done successfully. On March 10, the operating speed was 1.0, and on March 14, the air intake test performance was 1.0, with the maximum speed reaching 100.6%. In the whole test process, the performance of the core engine was stable without overtemperature vibration. And this completed the group responsibility target in 2020 ahead of the schedule.

The results of the first core engine of wide body airliner [COMAC C919], C2XC-101, is not only the first to verify the matching ability of each subsystem of the core engine, but also an important platform to verify the key technology research results. The successful completion of the air intake state test marks that the performance of each component of the core engine and its matching meet the design expectation preliminarily, which lays a solid foundation for the subsequent high-altitude test of the core engine and the overall test…

Something I have observed：
1. WS-15 is actually not very behind of WS-20
2. XAEC has started a new project last year, though I don't know what it is
3. QC-400 technology has been validated and wait for the senior government's approvement for formal development
4. WJ-10 project went smoothly
5. WS-13, probably also including WS-17 will enter mass production
6. WS-19 timeline is far behind WS-15, not like some people boasted it is quite near to WS-15

Hmmm??

1. ... but since WS-20 is far behind (at least our expectations), isn't then WS-15 also behind?
2. ?
3. ?
4. what is WJ-10?
5. I thought WS-17 is a hoax?
6. That is IMO not a surprise.

1. Well，at least not that bad in my opinion. Russians has recently said their Su-57 used idz 30 may enter service after 2025, I think WS-15 should be ahead of that if everything goes well. I guess WS-20 should get cerification in this year and enter small batch production the next year, and WS-15 may be one or two years later.
2. As I said I don't know what it is, but it should be a newly developped turbofan type. XAEC is the manufacture of WS-20 but this project is not WS-20 because it is started last year
3. QC-400 is 40MW gas turbine developed by Liming used by next generation destroyer/frigate
4. Turboprop used by KJ-600
5. WS-17 has taken flight with L-15 in 2016, but I don't know how it goes now.

What is the source of this information?

Can some one post Mean Time Between Overhaul (MTBO) of various chinese ans Russian engines ?

How old are these pics? IS it latest WS 10 going into J11 ?

Noticed that someone is trying to use hammer on the engine. Is that normal? or something is stuck?

that is a TORQUE SCREW DRIVER that need Hammer to rotate the driver axis.

As OBLiTeRate said, it is commonly used when changing the brake rotator on car. But yes normally it is something very tight. And I think it is called IMPACT screw driver.

Does China have single crystal blades?

Obviously. They've had single crystal blades since the 90s ... http://en.cnki.com.cn/Article_en/CJFDTotal-GXGC199701003.htm

Via by78/SDF:

An interesting image, which seems to suggest that Y-20 is being used as an engine test platform. I wonder what engine is being tested here.

At least it looks substantially slimmer/smaller than a regular D-30KP-2/WS-18.

Could it be possible this is the WS-15 we've been waiting for? Certainly would make sense for the Y-20 to be a test bed for it.
